5X00501G01 伺服驱动器

描述
5X00501G01硬件设计使伺服驱动器上电时，伺服输出电源关闭。随着没有电流流向伺服阀，它 在其机械偏置调整的影响下，5X00501G01在上电前假定状态。此外，线圈驱动的D/A转换器直到接收到第一输出模式才开启。作为微控制器启动序列的一部分，电源被打开，然后将图案写入表示0伏的5X00501G01线圈驱动D/ a转换器。结果是伺服输出在软件控制下，伺服驱动器和伺服阀之间没有电流流动，也没有发生阀的运动。

5X00501G01伺服驱动器将不会保持在启动模式，除非检测到诊断错误。
如果满足以下所有条件，伺服驱动器将从启动模式转换为本地模式
函数执行并返回“normal”或“ok”状态码:

EPROM校验和检查。
从EEPROM读出配置常数。
当PE引脚为1时，进入出厂配置模式。
EEPROM校验和检查。

Description
The 5X00501G01 hardware is designed so that when the Servo Driver is powered-up, the power supply to the servo output is turned off. With no current flflow to the servo valve, it is left under the inflfluence of its mechanical bias adjustment, the 5X00501G01 assumed state prior to power-up. In addition, the coil drive D/A converter is not turned on until it receives the fifirst output pattern.As part of the microcontroller’s start sequence, the power supply is turned on, and then a pattern is written to the 5X00501G01 coil drive D/A converter representing 0 volts. The result is that the servo output is under software control, no current flflows between the Servo Driver and the servo valve, and no valve movement has occurred.

The 5X00501G01 Servo Driver will not remain in Start mode unless a diagnostic error is detected.
The Servo Driver transitions from Start to Local mode if all of the following
functions execute and return “normal” or “ok” status codes:

Program the FPGA.
Initialize default PI constants.
EPROM checksum check.
Read out confifiguration constants from EEPROM.
Go to Factory Confifigure Mode if PE pin is 1.
EEPROM checksum check.
RAM read/write test.
UART scratchpad read/write test.
Shared memory readback check.
